Title: Magnetic recording and reproducing device
Inventor: HONJIYOU MASAHIRO
IPC: G11B5/027
Filed: 1984-06-06
Abstract: PURPOSE:To improve the S/N of a chrominance signal by limiting a luminance signal band to a prescribed amount only during a period where a color burst exists at recording or reproduction in the chrominance carrier signal reducing, converting and recording system. CONSTITUTION:The luminance signal and the chrominance signal are separated from an input video signal (a) by a comb line filter 20. When a control signal (d) reaches a high level, a switch SW1 is closed to the position of an LPF21 to limit the luminance signal band. Thus, a chrominance signal component (3.58MHz) not eliminated by the filter 20 is eliminated completely and no noise is generated. While the cutoff frequency of the LPF22 is nearly 4MHz, that of the LPF21 is designed as nearly 2MHz. The noise generated in the reproducing system in reduced by applying similar switching in the LPFs 24, 25 at reproduction and the S/N of the color burst of a reproduced video signal (e) is improved.

IPC: H04W88/02
Filed: 1999-04-23
Abstract: PROBLEM TO BE SOLVED: To suppress transmission amplitude at a peak without increasing number of filter arithmetic circuits. SOLUTION: An envelope calculation section 113 calculates amplitude of a transmission signal after multiplexing. In the case that the calculated amplitude exceeds a permissible amplitude, a correction coefficient calculation section 114 calculates a correction coefficient that is a difference between the amplitude before the correction and the amplitude after the correction. Multiplier sections 115, 116 multiply a filter coefficient with the correction coefficient to calculate the correction value. Subtractors 119, 120 subtract the correction value from a transmission signal after the filter arithmetic operation.

Title: Reagent and method for immunonephelometry
Inventor: KIMURA AKIRA
IPC: G01N33/531
Filed: 1993-04-19
Abstract: PURPOSE:To accurately measure an insoluble immune complex generated through an antigen-antibody reaction by suppressing the nonspecific reaction with the use of a reagent containing a quaternary ammonium salt. CONSTITUTION:One or more kinds of quaternary ammonium salt among choline chloride, choline bromide, choline iodine, choline bitartrate, acetylcholine chloride, betaine hydrochloride, etc., are selected. A using reagent contains the selected quaternary ammonium salt. An insoluble immune complex generated in an antigen-antibody reaction is optically measured with the use of this reagent without using an insoluble carrier such as latex or the like. The using amount of the quaternary ammonium salt is adjusted to keep 0.1-10.0%, preferably, 0.3-3.0%. If the quaternary ammonium salt is used smaller than 0.1%, the nonspecific reaction cannot be sufficiently restricted. If the quaternary ammonium salt is used not smaller than 10.0%, it hinders the generation of the insoluble immune complex required for the measurement.

Comparison of the pressure with that for reference press fit is performed at an intermediate point of its stroke wherein progress of the stroke is kept on as it is when the pressure is within an allowable range and a state is decided as unusual when the pressure is outside the allowable range. When a load for press fit is arrived at the load for automatic cut-off, a feed of the working spindle 2 is suspended and it is checked if that point coincides with an instruction point of movement. When the load is within the allowable range, it is confirmed that the part W1 is seated over the spindle W2 normally by required fitting pressure.

Abstract: PROBLEM TO BE SOLVED: To continuously and excellently measure rays of various kinds of intensities, in a luminous energy measuring method which converts a ray to a current with a photodiode to which a bias voltage is applied and amplifies the current with an operational amplifier. SOLUTION: A bias power source 38 is connected with a photodiode 32 by using an analog switch 36 which operates at a high speed when the intensity of a ray to be measured is high and a photo-MOS relay 35 whose leakage current is very small.

When the intensity of a ray to be measured is middle, an off state is obtained with the analog switch 36, and the luminous energy of a ray in a range from high intensity to middle intensity can be continuously measured. When the intensity of a ray to be measured is low, an off state is obtained with the photo-MOS relay 35 and the luminous energy of a ray in a range from middle intensity to low intensity is measured with high precision in the state of very small leakage current.
